Hi there,
our current ironport setup is 1 IP interface and 1 listener to handle all inbound/outbound email traffic. Is it possible to create a second IP interface with a new IP on the same subnet, that will be NAT'd to a different external IP address?
Reason for this is we want normal mail flow to go out on our existing external IP since it has built a reputation, now we would like to send email out on a different external IP for marketing purposes.
Thank you for any help in advance.

I've tried adding another IP interface, and a new listener associated with it. But when I do all mail flow wants to use that new IP interface.

Hi Christina,
Please review the below article to understand how delivery interface is selected.

I would think based on the default gateway and lower IP on the subnet the same interface would currently keep getting selected.
Thanks!
